Default Throttle body
I am currently doing the top end on a 03 cvo 103. Heads have been ported, 10.25:1 comp, forged pistons, cr575 cams, powertune duals, and tts mastertune. I have the opportunity to get a 51mm HPI throttle body for a great price. Is this advisable ? Also, do I need to go with 25° injectors.
Not chasing numbers, just want good "reliable" torque, for two-up touring.
Thanks in advance

That 51 would be a great addition to that combo.

BTW if the price is good on the 51, it's still quite a bit better than the stock one. Make sure the intake runners match closely on ID.
